Some header files and debug code for ACM

Personally feel that single-step debugging trouble and cost time, so I two years of time F4+watch basic not how to use, but because "view variable value" This demand always exist, and debugging often need to show a lot of things, printf write up and compare egg pain, happen in C + + 11 know the variable parameter template This new thing, so decisive to come to write the debug code.

Local debugging, written in the header file, and then only the local containing it, OJ ignored. [Local.h] =
